api/server: drop unused Config struct

The Server.cfg field is never referenced by any code in package
"./api/server". "./api/server".Config struct values are used by
DaemonCli code, but only to pass around configuration copied out of the
daemon config within the "./cmd/dockerd" package. Delete the
"./api/server".Config struct definition and refactor the "./cmd/dockerd"
package to pull configuration directly from cli.Config.
